Care & Installation

Covers a broad mix of hardware and small assemblies rather than one single part class. Before installing, compare the replacement part's shape, dimensions, and mounting points against the original — this category spans many distinct component types and a single generic description cannot guarantee fitment. Follow the service manual's torque and assembly sequence for the specific subassembly involved.
